DESCRIPTION

These routines copy chstr into the window image structure at and after
the current cursor position. The four routines with n as the last
argument copy at most n elements, but no more than will fit on the line.
If n=-1 then the whole string is copied, to the maximum number of
characters that will fit on the line.

The window cursor is not advanced, and these routines work faster than
waddnstr. On the other hand, they do not perform any kind of checking
(such as for the newline, backspace, or carriage return characters), they do not
advance the current cursor position, they do not expand other control characters
to ^-escapes, and they truncate the string if it crosses the right margin,
rather than wrapping it around to the new line.

RETURN VALUES

All routines return the integer ERR upon failure and OK on success
(the SVr4 manuals specify only "an integer value other than ERR") upon
successful completion, unless otherwise noted in the preceding routine
descriptions.

X/Open does not define any error conditions.
This implementation returns an error
if the window pointer is null.

NOTES

Note that all routines except waddchnstr may be macros.

PORTABILITY

These entry points are described in the XSI Curses standard, Issue 4.
